  • Triads in Supply Networks: Theorizing Buyer-Supplier-Supplier Relationships

    Past studies in supply chain management have focused on dyadic relationships (e.g., buyer-supplier), as all relationships in a network begin with a dyad. However, dyads do not capture the essence of a network. We posit in this paper that triads are the fundamental building blocks of a network. To begin considering triads in supply networks, we build on two extant bodies of literature — the buyer-supplier relationship and supplier-supplier relationship literature which offer us the context of buyer-supplier-supplier triads. By doing so, we are taking the first step toward cracking the internal dynamics of triads in supply networks. To build theoretical propositions, we apply balance theory and the structural-hole concept. We identify nine triadic archetypes of buyer-supplier-supplier relationships and state key propositions that aid in decision making in supply networks.

  • Using Confidence Intervals in Supply Chain and Operations Research (invited paper)

    Like research throughout the entire business discipline, supply chain management research has relied almost exclusively on hypothesis testing methods. This is unfortunate as hypothesis tests routinely are misinterpreted in scientific research. We explain the limitations of hypothesis testing and recommend the use of confidence intervals as the preferred inferential statistical method. In particular, the additional information provided by confidence interval methods in highlighted using several supply chain management examples. We conclude with a set of recommendations designed to enhance the quality of supply chain management research.
